Catalyst was contracted by Crowley to do a complete overhaul of its oil skimmer Tatitlek Star based in Valdez, AK and part of the Alyeska SERVs fleet. Due to a coatings failure, the T-Star had extensive corrosion on the exterior of the vessel below the water line which required the entire vessel to get re-skinned. The scope of work included a complete replacement of all hydraulic systems, electrical systems, re-powering, replacing thrusters, and an overhaul of the layout for conduction oil-skimming operations. Hanson Hydraulics spear headed the extensive hydraulic work to the various systems onboard and Alaska Marine Coatings did a full blast to the entire exterior and re-coated the vessel. This three month project was completed on time and on budget. The Tatitlek Star is back in service read to provide emergency oil response services.
